15 Claims.

This invention relates to a bracket for supporting a guide for directing and traversing a filamentary bundle or threadwhile being collected in the form of, or while being withdrawn from, a wound, twistedcake'or package.

While the bracket herein disclosed has been designed especially for association with the funnel guide and centrifugal spinning bucket in an artificial silk spinning machine for collecting recently spun and still unfinished filaments, it nevertheless is applicable for supporting similar relatively long guides which traverse longiutdinally and especially in situations where it may-be necessary or desirable to withdraw the guide from its scene of operation while still traversing, especially where a limited space is available for the withdrawal of the guide.

. In the specification and claims, the expression funnel guide is intended to cover guides whichare essentially equivalent in function to the funnel guide per se regardless of variations which may involve a departure from what is generally considered a true funnel shape.

In the drawings, illustrative of the invention,

Figure 1 is a side elevation, partially in crosssection, of the bra'cketand associated parts,

Figure 2 is a plan view of the bracket with the funnel guide'removed,

Figure 3 is a side elevation of the device showing the parts in an intermediate position,

Figure 4 is a side elevation of the device showing the funnel guide swung clear out of the way,

Figure 5 is a side elevation of a modified form of linkage, and Figure 6 is a plan view of the modified form of linkage shown in Figure 5.

Figures 1 to 4 show the device in position over a centrifugal box in a spinning machine. spinning box 2, shown in dotted outline, is housed within a casing 3 which is provided with a cover 5 which may be removed for facilitating removal of the spinning box. The cover of the casing is provided with a central opening 5 through which the funnel guide 6 may traverse. Two parallel rails or rods 1 and 8, which extend the full length of the machine, and which are reciprocated vertically by suitable known mechanisms (not shown) support the bracket between'two bearings 9 and I0 suitably spaced along the rods and fastened thereto, such as by being clamped or'bolted to a common plate H beneath the two rods.

The funnel guide 6 is supported at its upper portion or neck by a member having the form of a cylindrical sleeve l2 provided at its upper end with a flange l3, the opposite sides of which are in turn provided with upstanding ears M The I and IS. The external surfaces of the ears as well as the adjacent peripheral surface of the flange are flattened to provide a satisfactory pivotal bearing surface. This sleeve l2 telescopes within a cylindrical recess Within the upper face of the cup-like member I! which has an ovaloutline as viewed in Figure 2. The cup-like member is provided with a bore it through its bottom within which the funnel may slide. wo parallel arms l9 and extend from opposite ends of the cup-like member l1 and are provided with trunnions 2| and 22 extending outwardly therefrom at their other ends. These trunnions are pivotally disposed within upstanding ears 23 and Ed on the bearings 9 and it! upon the rails. The arms rest upon the top surface of the bearings 9 and H] which act to limit the clockwise motion of the arms as viewed in Figure 1. Each of these arms are provided with slots 5 and 25 and with offset or stepped portions 2'! and 28 which.coop-- erate with the other parts of the device in a manner which will appear from the description hereinafter.

The funnel supporting sleeve I2! is pivotally supported by means of the ears M and i5 within a yoke 28 at 3t and M. As shown, the other end of this yoke is branched and is provided with a pair of trunnions 32 and 33 which extend into and cooperate with the slots 25 and 26 respectively of the two bracket arms. This yoke 29 is provided with pivotal connections at 34 and with a pair of links 35 and 31 whose other ends are pivoted to upstanding ears 33 and 39 upon the cup-like member H. The distance from the pivotal axis intermediate of the yoke through 34 and 35 to the axis of the trunnions .32 and 33 thereof is substantially one-half the distance from the pivotal axis of the funnel supporting sleeve l2 'to the axis of the trunnions 32 and 33. A guide member 510 is suitably supported between the two bearings 9 and iii, such as by mounting upon the lower plate H. This guide 40- is of hook-like conformation, the body 4! of the hook portion being in the shape of a quadrant. The quadrant portion overhangs the base portion 32 of the hook-like guide, and, as shown, are-entrant slot 53 (see Fig. 4) separates the two portions. This guide member also has a portion projecting upwardly at the upper end of the quadrant portion M. The yoke 29, at its end removed from the funnel supporting end, is provided with a pin 4-5 which extends transversely between the forked elements of the yokeand is substantially coaxial with trunnions 32 and33. This pin is adapted to followabout the contour of the quadrant as will be hereinafter described.

In operation of the device, withdrawal of the funnel from the spinning box and its surrounding casing may be accomplished regardless of continuation of the reciprocating motion and regardless of the position of the funnel bracket with respect to its traverse merely by taking hold of the tunnel or the flange 53 about the funnel supporting sleeve and lifting it upwards. In doing so, the intermediate position of Figure 3 is attained. Thereafter, the whole funnel bracket may be swung about the trunnions 2i. and 22' of the arms into the position of Figure 4 where it rests by gravity, further motion of the pin 65 in the yoke being prevented by the upwardly projecting portion it of the guide member 4%.

Figures 5 and 6 show one side of the linkage of a modified form of bracket (primed reference characters being applied to the parts of the modifled form which correspond to the parts carrying unprimed characters in Figures 1 to 4) in which all of the relations hereinbefore described with respect to Figures 1 to 4 are maintained with the single exception that the axis of the pin 35 and the trunnions (5:52 being shown) on the yoke is offset from the pivotal axis of the trunnions, (2! being shown) of the arms (it being shown) of the bracket, This assures that no pivotal action or the racket arms l8 and 2%) can occur until after the funnel has been lifted into an intermediate position corresponding to that of Figure 3. In this embodiment the distance between the axis or the pin 45 and the pivotal axis of the funnel supporting sleeve IS in the yoke is twice the distance from the pivotal axis 34 where the links 236 and 3? are connected to the yoke to the axis of the The invention provides a mechanism forliiting a funnel and swinging it from spinning position in which the first part of the motion is a straight line motion so that no damage can befall the funnel as it is withdrawn from the casing surrounding a spinning bucket. In the second part of the motion, the funnel is swung while firmly held in fixed relationship to the several parts of the bracket into its idle position where it remains ready to be reinserted by a single movement of the hand of the operator.

While preferred embodiments of the invention have been disclosed, it is to be understood that changes and variations may be made without departing from the spirit and the scope of the in vention as defined by the appended claims.
